Description

  The present invention relates to a drainage connection member installed on a wall surface of a toilet room.

  A urinal that is connected to a drainage pipe provided on a wall and drains may be replaced with a new urinal from an existing urinal for reforming a toilet or the like. Generally, the mounting height of the urinal on the wall surface is often set so that the height of the lip end of the urinal becomes a predetermined height for compliance with regulations.

  At this time, if the height from the lip end to the drainage port in the existing urinal differs from the height from the lip end to the drainage port in the new urinal, the drainage pipe provided on the wall surface is the existing one. Since it is provided according to the urinal outlet, if you try to install the lip end height of the new urinal according to the lip end height of the existing urinal, it will be provided on the outlet and wall of the new urinal The height of the drains may be different.

  Conventionally, when the positions of the existing drainage pipe and the drainage port of the toilet bowl are different as described above, a drainage connecting member for connecting the drainage pipe and drainage port at different positions has been used. For example, as a conventional drainage connection member attached to a floor surface, one having a connecting pipe portion for eccentrically connecting an inlet connected to a drainage port of a toilet and an outlet connected to a drainage pipe is known. (See Patent Document 1). In this drainage connection member, since the position of the inlet relative to the outlet can be changed by changing the direction of the connecting pipe, even if the positions of the drainage pipe and the toilet outlet are different, it is possible to connect both it can.

  However, when the structure of the drainage connection member attached to the conventional floor surface is adopted for the drainage connection member attached to the wall, the lower end portion of the drainage pipe in the flow passage inside the drainage connection member depending on the attachment direction of the connection pipe portion There may be a location where the height is lower than. If a location lower than the height of the lower end portion of the drainage pipe is formed, a location where the inclination is upward toward the drainage pipe is formed in the drainage connection member, so that urine is collected in the drainage connection member It could have been.

  The present invention has been made to such problems, and it is possible to adjust the height of the outlet where the drain is connected to the inlet to which the outlet is connected, and to adjust the height of the outlet to a plurality. An object of the present invention is to provide a drainage connection member capable of suppressing the accumulation of urine inside the connection member.

  In order to solve the above problems, a first aspect is a first inlet connected to the outlet of the urinal, and a first outlet having an opening area larger than the opening area of the first inlet, And a second inlet, the first outlet being rotatably connected about a central axis of the first outlet, and a drainage pipe provided on a wall, And a wall-side connecting cylinder having a second outlet having an opening area smaller than two inlets, wherein the toilet connecting cylinder has the first inlet within the opening area of the first outlet. The wall-side connection cylinder is eccentrically disposed so that the lower end of the second outlet is equal to or less than the lower end of the second inlet when the wall-side connection cylinder is attached. And the height of the lower end portion of the inner peripheral surface of the toilet bowl connecting cylinder and the wall side connecting cylinder. The drainage connecting member is characterized in that the height from the lower end of the first inlet to the lower end of the second outlet is equal to or less than the height of the lower end on the first inlet side. It is.

  According to such a configuration, even when the height of the drainage pipe formed on the wall surface and the drainage port of the urinal is different, both can be connected. That is, since the first inflow port of the toilet bowl connected cylinder is eccentric with respect to the first outlet, the drainage pipe is connected by rotating the toilet bowl connected cylinder with respect to the wall side connected cylinder. The height of the first inlet to which the urinal outlet is connected can be adjusted with respect to the outlet. Therefore, even when the height of the drainage pipe formed on the drainage port of the urinal and the wall surface is different, both can be connected. In addition, since the second inlet has an opening area larger than that of the second outlet to which the drainage pipe is connected, the adjustment range of the first inlet of the toilet connection cylinder can be made larger.

  Moreover, according to such a structure, it can suppress that urine accumulates inside the drainage connection member. That is, since the first inflow port of the toilet bowl connected cylinder is eccentric within a range in which it fits within the opening area of the first outlet, the lower end of the first inflow port is the first one even if the toilet bowl connected cylinder is rotated. Not lower than the lower end of the outlet. And since the lower end part of the 2nd outflow port is eccentrically formed so that it may become below the lower end part of the 2nd inflow port in the attachment state of a wall side connecting cylinder, the inner circumference of the wall side connecting cylinder A surface may be formed to descend from the second inlet to the second outlet.

  Furthermore, the lower end portion of the inner peripheral surface of the toilet bowl connecting cylinder and the wall side connecting cylinder has the height of the lower end portion on the first inlet side from the lower end portion of the first inlet to the lower end portion of the second outlet. By being formed so as to be smaller than that, there is not formed a portion which is inclined upward toward the second outlet between the first inlet and the second outlet. Therefore, it is possible to suppress the accumulation of urine inside the drainage connection member.

  In the second aspect, in the first aspect, the inner peripheral surface of the wall-side connection cylinder further includes an insertion portion into which the drainage pipe is inserted, and the second flow of the insertion portion At the lower end portion on the inlet side, a stepped portion equal to or larger than the thickness of the drainage pipe is formed.

  When the drainage pipe is inserted inside the wall-side connection cylinder, the height of the lower end of the inner peripheral surface of the wall-side connection cylinder is increased by the thickness of the drainage pipe, and urine is collected inside the drainage connection member There is a case. However, the drainage pipe is inserted inside the wall-side connecting cylinder by forming a stepped portion with a thickness equal to or greater than the thickness of the drainage pipe at the lower end portion on the second inlet side of the insertion portion into which the drainage pipe is inserted. Also, the height of the lower end portion of the circumferential surface of the drainage pipe can be made equal to or less than the height of the upper end portion of the stepped portion. Therefore, according to such a configuration, even if the drainage connecting member is inserted and attached to the inside of the wall-side connecting cylinder, drainage can be prevented from collecting urine inside the drainage connecting member.

  According to the present invention, it is possible to adjust the height of the outlet to which the drainage pipe is connected to the inlet to which the drainage port is connected to a plurality of heights, and urine may be collected inside the drainage connection member. The drainage connection member which can be controlled can be provided.

It is fixed by bonding.

  The drainage port 4 of the urinal 1 and the inlet portion 11 of the drainage pipe 10 are different in height in the vertical direction, but are connected to each other by the drainage connecting member 20. That is, the drainage connection member 20 connects the drainage port 4 of the urinal 1 and the inlet portion 11 of the drainage pipe 10 provided on the wall surface W. By doing this, the urine disposed in the bowl portion 2 and the washing water for washing the bowl portion 2 pass through the drainage channel 3 and flow out to the drainage pipe 10 through the drainage connection member 20.

  The urinal 1 is attached to the wall W by a back hanger 6 fixed to the wall W. A recess 5 for hooking the back hanger 6 is formed on the rear surface of the urinal 1, and the back hanger 6 is hooked on the recess 5. Then, the lower side of the urinal 1 is passed through the bolt fixing washer 28 to the bolt fixing portion 23 of the drainage connection member 20 through the bolt fixing nut 27 through the urinal fixing hole 8 and the urinal fixing washer 26. It is fixed to the wall surface W by tightening with the urinal fixing nut 25. The drainage connection member 20 is fixed to the wall surface W by a wall fixing screw 24.

  Next, the drainage connection member 20 according to the first embodiment will be described with reference to FIGS. 3 and 4. FIG. 3 is an exploded perspective view of the drainage connection member 20 according to the first embodiment. FIG. 4 is an enlarged cross-sectional view of the vicinity of the drainage connection member 20 in FIG.

  The drainage connection member 20 includes a toilet connection cylinder 40 connected to the drainage port 4 of the urinal 1, and a wall side connection cylinder 60 connected to the inlet 11 of the drainage pipe 10 through the drainage pipe flange 13. It consists of The toilet connection cylinder 40 has a first inlet 42 connected to the outlet 4 of the urinal 1, and a first opening 42 provided on the downstream side of the toilet connection cylinder 40 and having a larger opening area than the first inlet 42. A first cylindrical portion 41 having an outlet 44 and a flange portion 45 formed on the outer peripheral surface side of the first cylindrical portion 41 are provided. Further, the wall-side connection cylinder 60 has a second inlet 62 to which the first outlet 44 is connected, and a second outlet 64 connected to the drain 10 through the drain flange 13.

<Description of toilet bowl connection cylinder>
Then, the structure of the toilet connection cylindrical body 40 of 1st Embodiment is demonstrated using FIG. FIG. 5 is a back view and a cross-sectional view of the toilet connection tubular body 40 of the drainage connection member 20 according to the first embodiment, and FIG. 5 (a) is a back view of the toilet connection tubular 40 It is sectional drawing in the AA line of Fig.5 (a).

  As shown in FIG. 5, the first cylindrical portion 41 of the toilet connection cylinder 40 has a first outlet 44 having an opening area larger than that of the first inlet 42. Further, the central axis 42 a of the first inlet 42 is formed eccentrically with respect to the central axis 44 a of the first outlet 44, and the range in which the first inlet 42 falls within the opening area of the first outlet 44 Are eccentric. That is, the entire opening of the first inlet 42 is formed so as not to protrude from the opening of the first outlet 44. In other words, the range in which the central axis 42a of the first inlet 42 can be eccentric to the central axis 44a of the first outlet 44 is the first opening 42 of the first inlet 42 in the rear view of FIG. The upper limit is the extent to which the opening of the outlet 44 is overlapped at one point, and it is formed so as not to be separated further by an offset.

  By doing this, when the toilet connection cylindrical body 40 is rotated and attached to the wall side connection cylindrical body 60, the lower end portion 42 b of the first inflow port 42 is closer to the lower end portion 44 b of the first outflow port 44. Can also be made lower. Therefore, although the details will be described later, the lower end portion 42b of the first inflow port 42 is the lower end of the first outflow port 44 even if the toilet connection tubular body 40 is attached to rotate with respect to the wall side connection cylindrical body 60. It does not become the height below section 44b. The lower end in the specification of the present application represents the lower end, and for example, in FIG. 5A, when the toilet connection cylinder 40 rotates about the central axis 42a, the lower end of the first inflow port 42 The positions of the lower end 44b of the first outlet 44 and the position of the lower end 44b of the first outlet 44 change along the first inlet 42 and the first outlet 44, respectively.

  In addition, a first insertion portion 48 for inserting the wall side connection cylinder 60 continuously to the first outlet 44 is formed in the first cylindrical portion 41 of the toilet connection cylinder 40, and By inserting the second inlet 62 of the wall-side connection cylinder 60 into the one insertion portion 48, the toilet connection cylinder 40 and the wall-side connection cylinder 60 are connected. The first insertion portion 48 is formed so as to expand in diameter by the thickness of the wall-side connecting cylinder 60 around the central axis 44 a of the first outlet port 44. As a result, when the wall side connecting cylinder 60 is inserted into the first insertion portion 48, the bottom end 44 b of the first outlet 44 of the toilet connecting cylinder 40 is connected to the wall side connecting cylinder 60. The lower end portion 62b of the second inlet 62 is prevented from rising upward. Therefore, in the cross-sectional view of the drainage connecting member 20 in which the toilet connecting cylinder 40 and the wall side connecting cylinder 60 are combined in FIG. 4, the lower end 44 b of the first outlet 44 and the lower end 62 b of the second inlet 62 are It turns out that it is the same height.

  Further, the inner circumferential surface of the first cylindrical portion 41 is smoothly continued from the first inlet 42 to the first outlet 64, and is formed with a horizontal gradient and a downward gradient. Therefore, for example, the unevenness such as the bellows shape is not formed. When a bellows-shaped unevenness is formed on the inner peripheral surface of the first cylindrical portion, a portion having an upward slope is formed at the fold portion of the bellows, so a portion where urine is collected is formed in the first cylindrical portion I will.

  In the drainage connection member 20 of the first embodiment, such an upward slope due to the unevenness is not formed at the lower end portion of the inner peripheral surface of the toilet connection cylindrical body 40 either. It is possible to suppress the accumulation of urine inside the cylindrical portion 41.

It is formed. Thus, the lower end portion of the inner peripheral surface of the second cylindrical portion 61 has the same height from the lower end portion 62b of the second inlet 62 to the lower end portion 64b of the second outlet 64, as shown in FIG. It has become. On the other hand, since the opening area of the second outlet 64 is smaller than that of the second inlet 62, the upper end portion of the inner circumferential surface of the second cylindrical portion 61 is halfway from the second inlet 62 to the second outlet 64. In the lower side.

  The lower end 64b of the second outlet 64 may be formed so as to be smaller than or equal to the lower end 62b of the second inlet 62, so that the second outlet 64 is located at the position shown in FIG. Also, the lower side may be formed. That is, in the drainage connection member 20 of the first embodiment, the range in which the opening of the second outlet 64 can be eccentric to the central axis 62 a of the second inlet 62 of the central axis 64 a of the second outlet 64 is The upper limit of the opening of the two inlets 62 at one point is the upper limit, and the distance is not shorter than that.

  Moreover, the wall side connection cylinder 60 is attached to the wall surface W in the state shown in FIG. That is, the central axis 62a and the central axis 64a shown in FIG. 6 (b) are attached to the wall surface W in the horizontal direction, and as shown in FIG. 6 (a), viewed from the direction of the central axis 62a. It is attached to the wall W such that a straight line connecting the central axis 62a of the second inlet 62 and the central axis 64a of the second outlet 64 in a front view is vertical.

  By doing this, when the wall side connecting cylinder 60 is attached to the drainage pipe 10 via the drainage pipe flange 13, the height of the lower end portion of the inner peripheral surface of the wall side connecting cylinder 60 is set to the second The lower end 62 b of the inlet 62 to the lower end 64 b of the second outlet 64 may have a horizontal slope or a downward slope. That is, the height of the lower end of the inner peripheral surface of the wall-side connection cylinder 60 is from the lower end 62 b of the second inlet 62 to the lower end 64 b of the second outlet 64, and the lower end 62 b of the second inlet 62 It can be made to be equal to or less than the height of the lower end of the side. Further, in the second cylindrical portion 61 as well as the first cylindrical portion 41, the bellows-like unevenness and the like are not formed. Therefore, it can suppress that urine accumulates inside the 2nd cylinder part 61 of wall side connection cylinder 60.

  In addition, about the attachment with respect to the wall surface W of the wall side connection body 60, as long as the lower end part 64b of the 2nd outflow port 64 becomes below the lower end part 62b of the 2nd inflow port 62, it may attach slightly. Absent.

  On the outer peripheral surface of the second cylindrical portion 61 of the wall side connecting cylinder 60, a convex portion 68 which defines the rotational position of the toilet connection cylindrical body 40 with respect to the wall side connecting cylinder 60 is formed. The convex portion 68 is engaged with one of the first concave portion 50 and the second concave portion 52 formed one by one above and below the first outflow port 44 (see FIG. 5). The first recess 50 and the second recess 52 are formed on the vertical straight line connecting the central axis 42 a of the first inlet 42 and the central axis 44 a of the first outlet 44, and the first recess 50 is On the side where the first inlet of the first outlet 44 is approaching, the second recess 52 is formed on the side where the first inlet of the first outlet 44 is away. Therefore, by engaging the convex portion 68 formed on the wall-side connection cylinder 60 with either the first recess 50 or the second recess 52, the toilet-connection cylinder 40 can be made into the wall-side connection cylinder 60. It can be rotated by 180 degrees for connection.

When engaged with the convex portion 68 of the side connection cylinder 60, the central axis 42 a of the first inlet 42 is eccentric downward with respect to the central axis 44 a of the first outlet 44. Moreover, in any case of FIG. 7 (a) and FIG.7 (b), the state of the wall side connection cylinder 60 does not change. Therefore, the distance d2 between the central axis 42a of the first inlet 42 and the central axis 64a of the second outlet 64 in FIG. 7A is the same as the central axis 42a of the first inlet 42 in FIG. 7B. It is larger than the distance d3 between the two outlets 64 and the central axis 64a.

  As described above, in the drainage connection member 20 according to the first embodiment, the toilet connection tubular body 40 is rotated and connected to the wall side connection tubular body 60 so that the first inflow port 42 to the second outflow port 64 is connected.

In the state, or from the lower end portion 44 b of the first outlet port 44 to the lower end portion 62 b of the second inlet port 62, the lower side. Therefore, a recess is not formed between the first outlet 44 of the toilet bowl connecting cylinder 40 and the second inlet 62 of the wall-side connecting cylinder 60 in which the urine flowing from the urinal 1 is collected. Therefore, the lower end portion of the inner peripheral surface from the first inlet 42 of the first cylindrical portion 41 of the toilet connecting cylinder 40 to the second inlet 62 of the second cylindrical portion 61 of the wall-side connecting cylinder 60 has a horizontal gradient And down slope.

  The wall-side connecting cylinder 60 has the central axis 62a of the second inlet 62 upward with respect to the central axis 64a of the second outlet 64 to which the drainage pipe 10 is connected via the drainage pipe flange 13. The second outlet 64 is mounted in an eccentric state, and the second outlet 64 is formed such that the height of the lower end 64 b of the second outlet is less than or equal to the lower end 62 b of the second inlet 62.

  Therefore, the height of the lower end portion of the inner peripheral surface of the second cylindrical portion 61 of the wall-side connection cylinder 60 is the second flow from the lower end portion 62 b of the second inlet 62 to the lower end portion 64 b of the second outlet 64. It is formed to be equal to or less than the height of the lower end portion on the inlet 62 side. That is, the height of the lower end portion of the inner peripheral surface of the second cylindrical portion 61 of the wall-side connection cylinder 60 is lowered from the lower end portion 62b of the second inlet 62 to the lower end portion 64b of the second outlet 64 It is formed of a gradient.

  Therefore, as described above, in the drainage connection member 20 of the first embodiment, when the convex portion 68 of the wall-side connection cylinder 60 is engaged with the first recess 50 of the toilet connection cylinder 40, the toilet connection cylinder The height of the lower end portion of the inner peripheral surface of the first cylindrical portion 41 of 40 and the second cylindrical portion 61 of the wall side connection cylindrical body 60 is from the lower end portion 42 b of the first inlet 42 to the height of the second outlet 64. The lower end 64 b is formed so as to have a height equal to or less than the height of the lower end on the first inlet 42 side.

  Then, the case where the convex part 68 of the wall side connection cylinder 60 is engaged with the 2nd recessed part 52 of the toilet connection cylinder 40 of FIG.7 (b) is demonstrated. In FIG. 7 (b), the first inlet 42 is connected to the wall-side connecting cylinder 60 in a state of being eccentrically downward with respect to the first outlet 44.

  Since the mounting direction to the drainage pipe 10 does not change via the drainage pipe flange 13 of the wall-side connection cylinder 60, when the convex portion 68 of the wall-side connection cylinder 60 is engaged with the second recess 52 of the toilet connection cylinder 40 The second recess 52 is on the upper side, and the first recess 50 is on the lower side. Therefore, in the state shown in FIG. 7 (b), the first inflow port 42 of the toilet connection cylindrical body 40 is in a state of being eccentric to the lowermost side.

  However, as described above, since the first inlet 42 is eccentric to the extent that it falls within the opening area of the first outlet 44, the lower end 42b of the first inlet 42 is closer to the lower end 44b of the first outlet. It does not go low. Therefore, as shown in FIG. 7B, even when the convex portion 68 of the wall-side connection cylinder 60 is engaged with the second recess 52 of the toilet connection cylinder 40, the lower end of the first inflow port 42 The portion 42 b to the lower end 44 b of the first outlet 44 can be formed with a horizontal slope or a downward slope.

  Therefore, as described above, in the drainage connection member 20 of the first embodiment, when the convex portion 68 of the wall-side connection cylinder 60 is engaged with the second recess 52 of the toilet connection cylinder 40, the toilet connection cylinder The height of the lower end portion of the inner peripheral surface of the first cylindrical portion 41 of the body 40 and the second cylindrical portion 61 of the wall side connection cylindrical body 60 is from the lower end portion 42 b of the first inlet 42 to the second outlet 64 The lower end portion 64 b of the lower end portion 64 b is formed to be equal to or less than the height of the lower end portion on the first outflow port 42 side.

  Thus, in the drainage connection member 20 of the first embodiment, the toilet connection cylinder 40 is rotated and attached to the wall-side connection cylinder 60, and the height of the first inlet 42 to the second outlet 64 is Even if adjusted, from the lower end portion 42b of the first inlet 42 in the first cylindrical portion 41 of the toilet connecting cylinder 40 to the lower end portion 64b of the second outlet 64 in the second cylindrical portion 61 of the wall-side connecting cylinder 60 Since no upward slope is formed, accumulation of urine in the flow path inside the drainage connection member 20 can be suppressed.

  Further, since the second inlet 62 has an opening area larger than the second outlet 64 to which the drain pipe 10 is connected via the drain flange 13, the first inlet of the toilet connecting cylinder 40 is formed. The adjustment range of 42 can be made larger. That is, since the height of the first inlet 42 of the toilet bowl connecting cylinder 40 is adjusted by rotating with respect to the second inlet 62 of the wall side connecting cylinder 60, the opening area of the second inlet 62 is If it becomes large, the adjustment range of the toilet connection cylinder 40 rotated with respect to the 2nd inflow port 62 can also be enlarged.

  Further, a stepped portion 90 is formed at an end of the second insertion portion 86 on the second inlet 82 side, and the inlet portion 11 of the drainage pipe 10 is inserted until it abuts on the stepped portion 90. Further, it is also preferable that the inlet 11 of the drainage pipe 10 be processed in advance so as to abut on the step 90 of the wall-side connecting cylinder 60 when the drainage connecting member 30 is attached to the wall W. Further, the wall side connection cylinder 80 and the drainage pipe 10 are connected to the toilet bowl by using an adhesive or a sealing material (not shown) between the inner peripheral surface of the second insertion portion 86 and the outer peripheral surface of the drainage pipe 10. It is connected so that water does not leak from between the cylindrical body 80 and the drain pipe 10.

<Description of Wall Side Connection Tube>
The wall side connection cylinder 80 in the drainage connection member 30 of 2nd Embodiment is demonstrated using FIG. As shown in FIG. 9, the wall-side connecting cylinder 80 according to the second embodiment is connected to the second inlet 82 connected to the first outlet 44 of the toilet connecting cylinder 40 and the second inlet 82. A second cylindrical portion 81 having a second outlet 84 formed eccentrically and a second insertion portion 86 into which the drain pipe 10 is inserted are provided. Since the second inlet 82 is inserted into the first insertion portion 48 of the toilet connection cylinder 40, the outer diameter thereof is substantially equal to the inner diameter of the first insertion portion 48. Further, in the second insertion portion 86, since the drainage pipe 10 is inserted, the inner diameter of the second insertion portion 86 and the outer diameter of the drainage pipe 10 are substantially equal.

  Further, as shown in FIG. 9B, at the position where the step portion 90 is formed in the side view, that is, at the boundary portion between the second cylindrical portion 81 of the wall side connection cylindrical body 80 and the second insertion portion 86.

As shown in FIG. 9, the central axis 86a of the second insertion portion 86 is formed eccentrically downward with respect to the central axis 82a of the second inlet 82, and the lower end of the second insertion portion 86 is further formed. The portion 86 b is lower than the lower end 82 b of the second inlet 82. Therefore, as shown in FIG. 9A, the second outlet 84 formed at the boundary between the second cylindrical portion 81 and the second insertion portion 86 is also formed eccentrically with respect to the second inlet 82. The upper side of the opening shape of the second outlet 84 is the inner diameter of the second insertion portion 86, and the lower side is the inner diameter of the second inlet. That is, in the state where the wall side connection cylinder 80 is attached to the drain pipe 10, the second outlet 84 is such that the lower end 84b of the second outlet 84 is equal to or less than the lower end 82b of the second inlet 82. It is formed eccentrically.

  In addition, the shape of the 2nd outflow port 84 in the wall side connection cylinder 80 of 2nd Embodiment is not limited to the shape mentioned above, For example, circular shape, elliptical shape, etc. may be sufficient. Further, as described above, the opening shape of the second outlet 84 is a shape in which the overlapping portion of the two circles is extracted.

  The central axis 86 a of the second insertion portion 86 is the central axis 82 a of the second inlet 82 so that the lower end 84 b of the second outlet 84 is formed to be smaller than or equal to the lower end 82 b of the second inlet 82.
